Anton Hansson cb8276fa93 Put DEVICE/PRODUCT overlays in different partitions 
This change changes auto-generated RROs from DEVICE_PACKAGE_OVERLAYS
to be generated in the vendor partition, as opposed to /product where
they were generated in the past.

Note that PRODUCT_PACKAGE_OVERLAYS continue generating RRO packages
to /product, which means that a single app can be overlayed from
different partitions. These RROs have been given module and package
names based on their location.

Bug: 127758779
Test: verify noop on presubmit targets

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
